I know the early 2000's 4EATs call for Dexron III.

Dex VI is supposed to be backwards compatable in auto boxes.

Has anyone tried Dex VI in a 4EAT?

Why not just go to the new Subaru HP ?
Subaru HP is a dealer-only item. Hassle factor. Expensive dealer prices.

I'd much rather use something readily available at discount prices from parts stores, Wally's, etc.

Valvoline says their Dex VI is synthetic, ditto for their MaxLife ATF. I know the Maxlife works well in a 4EAT. Just windering about the Dex VI.

Now, why does this thread NOT show up on my screen?

I've been using the Valvoline DEX-6 ATF in my 2005 forester for the past Month. So far, so good. Very smooth shifting.

Nope.

Dexron is not the right fluid, most Japanese makers specify a high-torque fluid and it must meet JASO M315-1998, now called JASO-1A standards.

It's usually sold as a 'multi-vehicle' fluid, just look for the JASO 1A approval on the jug. Don't get confused because it says it CAN be used as Dexron - it also CAN be used to oil the hinges on your garden gate......

Fuchs 4400,
Castrol Maxlife Multi-Vehicle,
Castrol TransMax E,
Kendall VersaTrans,
Honda ATF-Z1,
Motul Technosynth ATF,
Mobil 1 Synthetic ATF,
these are all syn or semi-syn ATFs that meet the std.

My manual calls for DEXRON III in my 2005 forester which is why I would only use DEX3 or DEX6 since it's backwards compatible and offers several improvements over DEX3. I believe model years 2006 and up use the Subaru HP-ATF which is different.

will bump the thread.

how many of you guys are using dex 6 in your trannies? any issues? i'm especially concerned with hot performance. i know that dex6 is fully synthetic, not like dex3 g/atf hp, which are synthetic blended products (despite any manufacturers claims). so it should give better cold behavior, since its viscosity is lower. but how's tranny life when it's hot? anyone using it for racing?

I had to buy an O-ring at the local Subaru dealer due to a leaking power steering pump. It's 2 bucks and the dealer is on the way to the local stores.

Anyway, I asked the parts guy, who has been at this dealer for decades, if I need the special HP Subaru fluid or if I can use Dex VI as I expected it to be re-branded Dex VI. Well, HP is Dex VI as I expected.

Just like Nissan Matic-D is Dex III. Its just rebranded. Which is good, cause I have a Buick that uses DexronVI as well.
